Medium- to Long-term Environmental Targets: The entire Nihon Kohden Group

Nihon Kohden considers the following items to be the Company’s business risks: Disruption of the supply chain due to natural disasters caused by climate change, and production delays due to insufficient water resources. 
We revised our medium- to long-term environmental targets, as the Japanese Government declared a target of achieving carbon neutrality by 2050. In order to realize a carbon-free society, we also set KPI for the reduction of CO2 emissions in the three-year business plan, BEACON 2030 Phase I, which started in FY2021.
We will continue our efforts to reduce Scope 3* CO2 emissions by providing environmentally friendly products and cooperating with our business partners in the supply chain. We will also identify and take action to resolve the Group’s environmental issues by monitoring resource inputs and energy use in the entire Group, disclosing water usage and Scope 1 and 2* CO2 emissions data, and setting science based targets* (SBT).
* Scope 1: All direct emissions from the Company's use of fuel
* Scope 2: Indirect emissions from the use of energy (mainly electricity) produced by other companies
* Scope 3: Other indirect emissions in the Company's supply chain
* Science Based Targets are greenhouse gas emissions reduction targets set by each company for 5 to 15 years in the future in line with the levels sought under the Paris Agreement.
Environmental targets for FY2050
We aim at zero greenhouse gas emissions throughout the entire product life cycle (carbon neutrality by 2050) by reducing greenhouse gas emissions from business activities, providing environmentally friendly products, and cooperating with business partners in the supply chain.
Environmental targets for FY2030
We have set environmental targets for FY2030 based on SBT* and are taking action to achieve them with the aim of realizing carbon neutrality by 2050.(These targets will be revised when the target values based on SBT are finalized.)
(We are aiming at a 26% reduction compared to FY2013 within the scope of ISO 14001 certified sites.)
Established: April 1, 2021

ISO 14001 Certification

ISO 14001 certificate ISO 14001 certificate
One mark of our progress in this area is ISO 14001 certification for our head office and main production factory in Japan. The ISO 14001 Environmental Management System standard represents the ISO's (International Standards Organization) commitment to support sustainable development by giving companies the tools to assess and control the environmental impact of their activities, products or services.
  • The Tomioka Factory obtained ISO 14001:1996 certification in October 2001, and underwent a transitional review for ISO 14001:2004 in October 2005.
  • Our head office and production department were integrated and registered for joint certification in January 2007.
  • In 2017, we completed transition to ISO 14001:2015, and underwent expansion inspections at the Advanced Technology Center and the Tomioka Second Factory.
  • In 2019, the Asaka Office obtained new certification and joined the Ochiai/Tokorozawa site.
  • In January 2022, the Eastern Japan Logistics Center obtained new certification and joined the Ochiai/Tokorozawa site in January 2022.
Currently, we conduct business activities at five sites, i.e., Ochiai/Tokorozawa Site: head office and development division; Tsurugashima Site: distribution of consumables and repair and maintenance of medical electronic equipment; Kawamoto Site: development of consumables and safety/reliability testing of medical electronic equipment; and Tomioka Site: manufacturing and spare parts supply.
The Fujioka Site was closed and related departments were relocated to the Tsurugashima Site and the Tomioka Site in May 2021. We discontinued environmental activities at this site.

In line with the principles of the United Nations Global Compact which Nihon Kohden signed in July 2015, we are driving activities to incorporate elements into its environmental targets, including preventative approaches to environmental issues, leadership in taking responsibility for the environment, as well as the development and widespread adoption of environmentally friendly technologies.

In-House Environmental Awareness Training Program

Introductory education is held for new employees to facilitate their awareness and understanding of general environmental issues, regulatory and legal compliance, ISO 14001 mechanisms, and the initiatives pursued by Nihon Kohden, as well as our Environmental Philosophy and Environmental Policy, details of targets, specific examples, and the need for full participation of all employees.
Employees working on five sites that have obtained ISO 14001 certification are educated every other year to deepen their awareness of relevant subjects, including changes in the social environment such as law revisions, Nihon Kohden’s Environmental Policy, environmental targets, and the relationship between the activities of each division.
In addition, in order to deepen awareness of environmental issues, we conduct e-learning once a year for all domestic employees.

Awareness Raising Activities
In FY2016, we established an annual Environment Day on June 5 during which we make known to all employees the need for environmental activities.

Green Procurement

As part of our efforts to provide eco-conscious products to the market, we promote procurement of parts, materials, and finished products which have a low environmental impact according to the following policy (green procurement).
1. Prioritize purchasing from suppliers conducting ambitious environmental conservation activities while also excelling in areas that include quality, pricing, delivery times, and services
2. Prioritize the purchase of toxic substance-free products

Requests to Our Suppliers

To uphold our green procurement policy, the Nihon Kohden Group asks its suppliers to practice environmental conservation in their business activities and supply products, parts, and materials that have a low environmental impact. We also ask them to provide an RoHS Declaration of Conformity and participate in various surveys.

Supplier-side Environmental Coservation

We ask all our suppliers to take measures for effective environmental conservation such as establishing an environmental policy, maintaining systems, and implementing education.

Supplying Low Environmental Impact Products, Parts, and Materials

To manage the chemicals that are used in our procured products, we request the following.

1. Create a control system for chemical substances used in products
2. Reduce toxic substances and implement green procurement of parts and materials that have low environmental impact

Chemical Substance Content Inspection

To evaluate the chemical substances in procured goods, we request all our suppliers respond to investigations of chemical substances in the goods. We require suppliers to provide certificates of compliance for materials used in RoHS compliant products.

Initiatives for Water Resources

Initiatives for using water resources in water-stressed areas

Nihon Kohden has identified water-stressed areas in each region in which the Company operates and evaluated risks accordingly. We utilized the Aqueduct Water Risk Atlas published by the World Resources Institute (WRI) and have confirmed that the following regions are relatively water-stressed areas compared to other regions: The U.S. and Mexico in the Americas, Germany and Italy in Europe, and India, UAE, and South Korea in Asia. Although no water-related issues have occurred in water-stressed areas at this time, we will continue to work on proper and efficient use and safe supply of water. We are currently collecting data at some overseas subsidiaries where we have not been able to obtain actual values.

Providing products with lower impact on water resources

Since the launch of its first hematology product in 1972, Nihon Kohden has developed and marketed hematology analyzers that are compact and easy to use. The latest models currently available provide improved safety, speed, convenience, and accuracy in blood testing. The product maintenance systems have also been improved. In addition, the amount of reagents used for diluting blood during testing and for cleaning the inside of the device has been reduced by approx. 20%* per year, resulting in a reduction in waste fluid discharge.
The MEK-1303 automated hematology analyzer and clinical chemistry analyzer
*  Results of comparison between our latest models; the MEK-1300 series automated hematology analyzers and the MEK-1303 automated hematology analyzer and clinical chemistry analyzer, and conventional models; the MEK-6500 series automated hematology analyzers, with 10 tests performed using each model per day.

Compliance with Laws and Regulations

Nihon Kohden has no serious issues of non-compliance with standards and regulations regarding water, payment of severe fines or penalties for violation of those standards and regulations, nor any serious water leaks.

Disclosure based on TCFD Recommendations

To realize our management philosophy that we contribute to the world by fighting disease and improving health with advanced technology, and create a fulfilling life for our employees, Nihon Kohden strives to earn the trust of our customers, shareholders, business partners, and society in all aspects of products, services, technology, financial position, and employee quality.
In recent years, activities aimed at achieving the UN Sustainable Development Goals have been promoted in order to respond to various cross-border social issues. The medical care we are involved in is becoming more and more complex due to various problems such as the aging society in developed countries, rising medical costs, lack of basic medical care in emerging countries, and widening medical disparities.
Under these circumstances, Nihon Kohden defined 12 material issues to be addressed through business and corporate activities. The Company also incorporated these non-financial targets into its three-year business plan, BEACON 2030 Phase I, which started in April 2021, in order to contribute to global social issues and SDGs.
As addressing climate change is one of the most critical social issues facing global society and one of the most significant management issues for us, Nihon Kohden expressed its support for the Task Force on Climate-related Financial Disclosures (TCFD) in May 2022. Nihon Kohden will address climate change with integrity to realize a carbon-free society as stated in our material issues and disclose information in line with the TCFD recommendations.
We aim to realize a sustainable society and increase our corporate value by further strengthening the coordination between our business strategy and sustainability strategy, and creating both economic and social value.

 Sustainability Policy


To promote sustainability, Nikon Kohden has established the Sustainability Promotion Committee, composed of the president, operating officers, and general managers, and Sustainability Promotion Meeting, composed of the representatives of 17 divisions. In July 2021, Nihon Kohden also established the Advisory Board consisting of four external experts* to incorporate outside perspectives on sustainability activities including measures to address climate change. 
The Sustainability Promotion Committee holds a meeting twice a year and formulates the policies and directions including measures on climate change. The president, who is the chairman of the Sustainability Promotion Committee, has the authority to evaluate and manage measures to mitigate climate change, and regularly reports to the Board of Directors about the progress and evaluation of the annual plan. The Board of Directors supervise measures on climate change.The Sustainability Promotion Meeting is held four times a year to establish and promote annual plans based on the policies and directions formulated by the Sustainability Promotion Committee and reports on the progress of those plans to the Sustainability Promotion Committee. Based on its three-year business plan, Nihon Kohden’s management has set KPIs (Key Performance Indicators) related to sustainability and assigned departments for each materiality. Members of the Sustainability Promotion Meeting, who represent the departments in charge of each materiality, report on the progress of sustainability activities and exchange opinions with other members at regular meetings. We strive to implement sustainability activities in its daily business operations, in close coordination with the Compliance Committee, Quality Control Committee, and Environmental Committee. The Advisory Board Meeting is held twice a year to discuss and advise on overall sustainability promotion, including actions on climate change.
Furthermore, in order to raise awareness of the SDGs within the company, we take actions such as educating employees in Japan and overseas through webinars.
* As one of the Advisory Board members was appointed as an outside director in June 2022, the Advisory Board currently consists of three members.

 Sustainability Promotion Structure
 Material issues and KPIs for realizing a carbon-free society


To understand the impact of climate change on business activities in Japan and internationally, Nihon Kohden has analyzed risks and opportunities mainly by management and members of the Sustainability Promotion Committee. Based on analysis of a 1.5℃ to 2℃ scenario as well as a 4℃ scenario, we have identified transitional and physical risks and opportunities over the short-term to FY2023, medium-term to FY2026, and long-term to 2029. We have also examined the business impact and possible countermeasures.
* A 2℃ scenario is to limit the global average temperature increase to 2°C above pre-industrial levels.
A 1.5℃ scenario is to hold the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels.
A 4℃ scenario estimates the global average temperature increase is to 4°C above pre-industrial levels.

 Long-term Vision, BEACON 2030
Assumption of each scenario 1.5℃/2℃ scenario 4℃ scenario
Society dimensions We assume that social changes toward a global decarbonization effort, which limits the average temperature increase to 1.5 to 2℃, will result in changes in laws and regulations, and technological innovation, affecting our business. We assume that extreme disasters and infectious diseases will increase and affect our business due to a 4℃ increase in the average temperature, even though the Paris Agreement and various policies to reduce greenhouse gases will be implemented.
Reference Transition risks: IEA (International Energy Agency): STEPS (The Stated Policies Scenario), NZE (Net Zero Emissions by 2050), SDS (Sustainable Development Scenario)
Physical risks: IPCC (Intergovernmental Panel on Climate Change), SSP2 (Shared Socioeconomic Pathways), RCP4.5, RCP6.0, RCP8.5
(Time period is 2030 to 2050) 
  • The outlook with a 1.5℃ to 2℃ scenario – Potential impact of climate change on our business
In the medical industry, demand for environment-friendly products and digital health solutions will increase because of strengthening laws and regulations and increasing customer awareness of the need to realize a carbon-free society. Costs are expected to increase as a result of the need to meet this demand, but further business opportunities are expected if our response is handled properly.
  • The outlook with a 4℃ scenario – Potential impact on our business due to climate change
In a society where decarbonization policies are not progressing well and extreme natural disasters are intensifying, it is expected that the healthcare system will need to be strengthened, especially in the areas of disaster medicine and emergency medicine. On the other hand, the procurement of parts, the supply of products, and sales and service activities may be disrupted significantly. 

Risk Management

The Board of Directors is responsible for establishing basic policies concerning risk management in overall Group business operations, and ascertaining the improvement and implementation status of the Group-wide risk management framework. The risks present in the execution of business activities have been classified into nine types, and the Risk Management Divisions and Risk-Related Committees have been assigned to each risk type. The Risk Management Divisions provide training and support to operating units and subsidiaries with regard to their assigned risk types, and report improvements to the system and their implementation status to the Board of Directors and the Risk Management Supervisory Division, which is tasked with improving and promoting the overall risk management system of the Nihon Kohden Group. The Risk-Related Committees report to the Management Council on matters including assessments of management system appropriateness, validity, and effectiveness for related risk types.

 Strengthening Our Risk Management System

Metrics and Targets

In order to address various cross-border social issues and achieve the Sustainable Development Goals, Nihon Kohden has defined 12 material issues to be addressed through business and corporate activities. The Company has also incorporated these non-financial targets into its three-year business plan, BEACON 2030 Phase I, and set environmental KPIs (Key Performance Indicators). To realize a carbon-free society, the Company has set KPIs for CO2 emissions, the number of models and sales ratio of environment-friendly products, and the amount of waste from disposal of products and parts.
